摘要
多路换向阀是工程机械液压系统中的关键部件之一。综述了多路换向阀的发展历程,分析了其发展背景及存在的关键问题。着重分析了最新的抗流量饱和技术、负流量控制技术和带电液负载敏感的负载口独立控制电液比例多路阀。展望了该领域今后的研究方向。
Directional-control-valves is one of the key components in the hydraulic system of construction machines. The development course of directional-control-valves is summarized and the developing backgrounds and main defects are analyzed. It is especially discussed that newly existed load-sensing compensation technology, negative control and electrohydranlic proportional directional control valves with electrohydraulic load sensing and separate controlling of meter-in and meter-out orifices. At last, the future trends of this field are presented.
